This S350 is smooth powerful and fun to drive. I have 6,000 miles on mine and it's the bast car I have ever owned including other Mercedes, Lexus, and Audi models. Interior is well laid out with all controls within easy access. My car gets 37 MPG on the highway and I am averaging over 31 MPG in mixed city and highway driving. 4 Matic works great in the rain or snow as well. This truly an exceptional ride, but be aware of expensive options as they are way over priced.
I recently traded in a 2011 BMW 535ix, which I found to be one of the most uncomfortable cars I have ever owned, on a 2013 S550, which is the most comfortable car I have ever owned. The car is absolute serenity to drive. No wind noise; no engine noise; no tire noise. The V8 is 430hp/520lb-ft of pure butter. Sure, the car is big and heavy, but it carries its heft very well and it does not claim to be the ultimate driving machine (whereas the BMW did, and it was far from it). The S550's adaptive air suspension is more butter, and it keeps the car stable and level, even during spirited driving.
At 570 miles the pulley on the alternator wore a hole in the bottom radiator hose. I was 450 miles from home in west Texas. The dealership took a hose off a new car on the showroom floor to get me on the road, however it turned out the water pump had an incorrectly formed flange. The nearest water pump was 10 days away in Germany. They rented me a car to finish my journey. Once the new water pump came in and the old one was replaced the dealer I bought the car from in Dallas sent a truck 250 miles west to pick up the repaired vehicle, haul it 450 miles back east to my driveway. The service was incredible and Mercedes has my highest praise. Just returned from a 2,000 mile trip to Minnesota.
Bought this Car in 2018 with 40k miles on it , it was a one owner vehicle in meticulous shape. In the 6 months I've owned the car I've had to change both front air struts(4800.00 at MB ) both control Arms and The motor mounts and transmission mounts also need to be replaced. The car is beautifully designed , but lacks a little bit in iron clad reliability compared to say the Lexus LS460. Beautiful and fun car to drive that turns heads, but be prepared to give this car constant maintenance attention as it tends to be really finicky particularly with the suspension.
Bought the 2010 S550 4-matic with every option as a lease return CPO at almost 1/2 the original purchase price at two years old and with 20K miles on the ode. Bought an extra 2 year warranty and have only had to use it once for the drivers wheel sensor. Dealership replaced all the wheel sensors just to make sure. Oil, brakes, windshield wipers, air filters and one set of tires is all I've put into this car with over 60K miles of almost daily use. Tires made a huge difference - bought Conti DWS and that made this car perfect in all weather and super quiet, including managing a foot of snow on the road. I've had no issues with transmission or engine - starts off the line fast in sport mode, rides smooth in comfort, shifts great with no hesitation between gears. I've owned over fifty cars (all types) and this car is one of the best. I'm 6'6" and the drivers seat fits perfect - If I want, I can put the seat back far enough so I can't reach the pedals. Massage, heated/cooled and fine leather seats are perfect for long trips. Oil changes at the dealer (MB-PDX) with a free loaner (due to the car being S-Class) has been great. 60K highway / freeway miles has averaged 20 mpg (per the panel). Finally, I can sell / trade the car for about 1/2 of what I paid which isn't too bad for driving this level of comfort.
